Answer 1

The cell will get dequeued using UICollectionView's recycler - the label itself stays at the recycled cell, so there's no need in re-allocating it, you just need to find where you placed it:

#define LABEL_TAG 100001

- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath{

    UICollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:@"cellIdentifier" forIndexPath:indexPath];

    UILabel *label = (UILabel*)[cell.contentView viewWithTag:LABEL_TAG];

    if (!label) {
        label = [[UILabel alloc] initWithFrame:CGRectMake(5.0, 90.0,90.0, 21.0)];
        label.textColor = [UIColor redColor];
        label.backgroundColor = [UIColor clearColor];
        label.font = [UIFont boldSystemFontOfSize:12];
        label.textColor = [UIColor colorWithRed:46.0/255.0 green:63.0/255.0 blue:81.0/255.0 alpha:1.0];
        label.tag = LABEL_TAG;
        [cell.contentView addSubview:label];
    }

    label.text = [NSString stringWithFormat:@"%@",[arrImages objectAtIndex:indexPath.row]];
    return cell;
}
